Analysis

  1. Different intervals - The trend of lines are almost same for different intervals, but smaller intervals give more details about the ups-and-downs of the count value.

  2. Different counting method - It doesn’t have very significant difference of fluctuation between ratio method and after method, the main trend for each plot is quite similar.

  3. Regular Season vs Playoffs - The plots of count values for Regular Season games are basically looks same as the plots for Regular Season + Playoffs games. For Playoffs games, although the data for Playoffs games are not that enough, but still can see the roughly trends. It approximatly flucduate similar as Regular Season.
